The magnitude of the force of gravity acting between the particles is:
The weight of each particle is:
Now let's plug in the numbers knowing that
, 
, 
and m1 and m2 are already given in kilograms. We get then:
N
N
N
This results shows us why we don't often see objects being attracted to each other, their mass is too small compared to the earth gravitational pull.

Explanation:
It is given that,
Mass of the box, m = 100 kg
Left rope makes an angle of 20 degrees with the vertical, and the right rope makes an angle of 40 degrees.
From the attached figure, the x and y component of forces is given by :
Let and
is the resultant in x and y direction.
As the system is balanced the net force acting on it is 0. So,
.............(1)
..................(2)
On solving equation (1) and (2) we get:
(tension on the left rope)
(tension on the right rope)
So, the tension on the right rope is 1063.36 N. Hence, this is the required solution.
